I agree on checking with the pros. I am sure we have some on this site but alot of us are not really trained in this complex area. What may work for a certain dog might be a train-wreck for another. There is some good advice given so far and some very bad info. also.
Check with a trainer = sounds like Big Lead might have something and Star1pup has given very good advice.
Good luck and keep us posted
